Here is a rope, on a triangle. On play, it will either fall to the left since it has more rope, fall to the right because it has a stepper slope, or it does neither.

The reason it stands still is that each side cancels each other out, meaning it stays still. Another reason is that it would make a perpetual motion machine if it was unbalanced. Let's say yes, it is unbalanced. The rope will tip to the left. Now, if we add a section under the rope, same rope, does not contribute to any pulling and pushing, it will keep on tipping, since one side is unbalanced, kinda like that wheel with mercury. If it is unbalanced and we added a rope underneath, we would make a perpetual motion machine, a machina capable of doing work by itself, so I could put like, a wheel and a motor, it would make electricity! YAY FREE ENERGY!! Saddly that isn't the case due to the laws of Thermodinamics, the first law states that no energy must be created or destroyed, meaning it's a constant, which sadly, eliminates the possibility of Free energy, but it does keep the thing going. The second law states that energy will tend to spread out, meaning due to stuf like friction and heat waste, energy would slowly leak out. Which is why the rope won't keep spinning. TL DR, the rope won't be unbalanced because it would break the Laws of Thermodinamics.
